Ted,

Based upon your response to the difference between the Heading and COG data items, it does not appear that there is any issue with the heading performance fo the autopilot. Per our phone conversation, it is recommended that
- you verify that only NMEA 0183 IN terminals of the E85001 PC/SeaTalk/NMEA 0183 communications interface have been interfaced to the the third party chartplotter. While it is possible to for the chartplotter to also receive data from the Raymarine system, a programmable NMEA 0183 Multiplexer would need to be installed between the NMEA 0183 OUT terminals of the E85001 the third party chartplotter's NMEA 0183 input port to prevent a data loop. Should you be uncertain about whether a programmable NMEA 0183 Multiplexer has been installed, has been properly programmed along with NMEA 0183 output settings within the Chartplotter to not loop data between the two systems. Should you be uncertain about the NMEA 0183 Multiplexer, then may want to consider disconnecting any leads connecting the third party chartplotter to the NMEA 0183 OUT terminals of the the E85001 PC/SeaTalk/NMEA 0183 communications interface.
- when commanding a chartplotter to follow a route, that you ensure that the navigation begin commanded by the chartplotter is specifying
----- navigation to the desired waypoint of the route which you are seeking to travel to first, and
----- the route is in the correct order (i.e. the route is not being navigated in reverse order)
- - the autopilot's Response Level adjusted to steer a tighter course ... increasing the number will cause the autopilot to steer a tighter course ... thereby reducing the magnitude of any S-ing. The data item XTE (Cross Track Error) is the indicator of how far the vessel is located from the course line at any time.
- the x30's software be updated to v3.05
